marine - Having to do with the ocean world or environment.
marine ecologist - A scientist who studies the ocean's ecology
plastic trash - scientists estimate the seas contain about 5.25 trillion pieces of this trash. Its combined weight: an estimated 269,000 metric tons.
Fish and other marine organisms can ingest tiny plastic fragments. This trash can then move up the food chain as seabirds, seals and other marine predators eat those fish.
plastics can work like sponges, soaking up and storing toxic chemicals. These include PCBs, pesticides and flame retardants. When ingested, such plastic can release the pollutants, triggering health problems.
ocean plastics also provide homes for germs, some of which can cause disease.
